Team develops a non-invasive method for profiling a person’s unique circadian rhythm
by BIH at Charité The circadian system and methods for determining CRs and chronotyping. (A) The role of the circadian clock in health and disease. A proper functioning clock ensures correct timing of physiological events such as sleep/wake cycles and contributes to sustain a healthy life (left). The disruption of CRs (right) is associated with...

Circadian rhythm may influence how well medications work and how much they might harm you
by Tobias Eckle, The Conversation Credit: Pixabay/CC0 Public Domain All living organisms on Earth are exposed to a 24-hour day-night cycle. This cycle is the reason why people rest during the darkness of night and are active during the light of day. Consequently, all human body functions also follow this daily rhythm, and the timing...

Circadian rhythm disruption found to be common among mental health disorders
by University of California, Irvine Credit: Unsplash/CC0 Public Domain Anxiety, autism, schizophrenia and Tourette syndrome each have their own distinguishing characteristics, but one factor bridging these and most other mental disorders is circadian rhythm disruption, according to a team of neuroscience, pharmaceutical sciences and computer science researchers at the University of California, Irvine. In an...

New connections between circadian rhythm and muscle repair identified
by Melissa Rohman, Northwestern University Credit: Pixabay/CC0 Public Domain Northwestern Medicine investigators have discovered a novel mechanism that connects circadian rhythm-controlled cellular metabolism and regeneration with muscle repair after injury, according to recent findings published in the journal Genes & Development. Clara Peek, Ph.D., assistant professor of Biochemistry and Molecular Genetics, was senior author of the...

Alcohol consumption is affected by a protein linked to the circadian rhythm, new research finds
by Patrick Lejtenyi, Concordia University Credit: Pixabay/CC0 Public Domain It’s a commonly heard question after New Year’s [celebrations]: “Why do we drink the way we do?” A group of researchers has found that at least some of it has to do with a particular protein in the part of the forebrain that regulates, among other...

Scientists uncover a circadian rhythm in heart cells that affects their daily function
by UK Research and Innovation Heart clocks regulate the daily variation in heart rate – Each heart cell has a clock that regulates the frequency of firing rate between day and night. This helps the heart to beat faster during the day and to sustain daily activities. Credit: Copyright MRC LMB A new study has...

How the circadian rhythm of the liver is regulated by muscle activity
by Institute for Research in Biomedicine (IRB Barcelona) Credit: Pixabay/CC0 Public Domain The biological clock/circadian rhythm is the mechanism that ensures that a certain physiological process takes place at a specific time of the day or night. It is coordinated by the brain at a general level, but each organ or tissue is also subjected to specific regulation....

Circadian Rhythm and Asthma
For hundreds of years, people have observed that asthma severity often worsens in the nighttime. One longstanding question has been to what degree the body’s internal circadian clock—as opposed to behaviors, such as sleep and physical activities—contributes to worsening of asthma severity. Harvard Medical School investigators at Brigham and Women’s Hospital and researchers at Oregon Health and...
